DeWalt DCD805
Best ValuePros

The DeWalt DCD805 is a versatile combi drill that handles decking screws with ease. Its 820 in-lbs of torque is enough for most softwood and composite decking, and the brushless motor ensures efficient battery use. Owner reviews praise its balance and low vibration during extended use.
It is lighter than the Milwaukee, making it a good choice for overhead work or long days. The 20V MAX system is widely available and compatible with many DeWalt tools. For the price, you get a reliable drill that will not let you down on a deck build.
Makita XFD131
Best LightweightPros
- Very light for the power
- Excellent build quality
- Star Protection battery system
Cons
- Chuck is plastic on some models
- Battery life could be better
The Makita XFD131 packs impressive torque (1,090 in-lbs) into a lightweight 3.9 lbs package. This makes it ideal for decking where you need to drive many screws without arm fatigue. The brushless motor is efficient, and the 2-speed gearbox gives you control.
Owner reviews highlight its comfortable grip and smooth operation. The LXT battery platform is one of the largest, so you can share batteries with other tools. It is a top choice for DIYers and pros who value a lighter tool without sacrificing power.
Bosch PS82-02
Best Compact BuildPros
- Very compact and light
- Good for tight spaces
- Solid Bosch reliability
Cons
- Lower torque than others
- Battery ecosystem smaller
The Bosch PS82-02 is a compact combi drill that excels in tight spaces, such as deck edges or under railings. Its 700 in-lbs of torque is sufficient for standard decking screws in softwood and composite materials. The short head length allows you to get into corners easily.
Owner reviews note its solid build and comfortable handle. It is not the most powerful, but for light to medium decking work, it is a reliable and nimble tool. The CORE18V batteries offer good runtime for the size.

Ryobi P251
Best Budget ChoicePros
- Very affordable
- Large battery ecosystem
- Good for occasional use
Cons
- Less durable than pro brands
- Slower driving speed
The Ryobi P251 is an entry-level combi drill that gets the job done for budget-conscious DIYers. With 750 in-lbs of torque, it can handle most decking screws in softwood and composite. The ONE+ battery system is one of the most affordable and widely available.
Owner reviews say it is a solid performer for occasional deck projects, though it may struggle with very hardwoods or long days of heavy use. It is a great value option if you are already in the Ryobi ecosystem or starting your tool collection.
What to Check Before Buying a Combi Drill for Decking
Decking screws are typically longer and thicker than standard screws. You need a drill with enough torque to drive them without stripping or stalling. Look for a model with at least 700 in-lbs of torque for softwood decking, and 1,000 in-lbs or more for hardwood or composite materials.
Battery voltage and amp-hour rating matter. A 20V or 18V system with a 4.0Ah or higher battery will give you enough runtime for a full deck. Consider the brand ecosystem if you plan to expand your tool collection.
Mistakes to Avoid
One common mistake is using a standard drill instead of a combi drill with a hammer function. While not always needed for decking, the hammer action helps if you need to drill into concrete or brick for posts or anchors. Another mistake is ignoring the chuck size. A 1/2-inch metal chuck is more durable and holds larger bits securely than a plastic one.
Do not overlook weight. A heavy drill will tire your arm quickly when driving hundreds of screws. Aim for a model under 5 lbs with battery for comfortable use over a full day.
